Additional information

Conclusion on classification

Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). All acute effect values were above 100 mg/L. Therefore, the substance does not need to be classified for acute hazard according to EU CLP (EC no. 1272/2008 and its amendments).

 

Long-term aquatic toxicity data are available only from a limit test with algae, Desmodesmus subspicatus, in which NOEC value of < 100 mg/L was determined. Furthermore, the substance is classified as not readily biodegradable. The log Kow is -2 (no experimentally determined BCF value is available). According to CLP, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) i, as well as the acute value according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:

- The substance has a chronic toxicity value of < 100 mg/L, but it is highly unlikely that the substance has a long-term effect value for algae below 1 mg/L as only ~20% inhibition was observed at 100 mg/L. Based on this information, the substance does not need to be classified for chronic hazard according to Table 4.1.1, (b) i.

- The acute toxicity values are all above 100 mg/L. Based on this information, the substance does not need to be classified for chronic hazard according to Table 4.1.0, (b) iii.

 

Overall, it can be concluded that the substance does not need to be classified for chronic hazard according to EU CLP (EC 1272/2008 and its amendments).
